We stayed up with Exploratorium scientist Ron Hipschman at the Lick Observatory in San Jose, California, for the best view we've had of Mars in a long, long time. At midnight on August 27, Earth and Mars passed closer to one another than they have in 60,000 years. Astronomers were on hand to tell us all about our nearest neighbor—its geography, orbit, and why both NASA and the European Space Agency have chosen this time to launch robotic missions to Mars.

Look behind the scenes into the process of scientific research and the people who do it - in the tropical Central American country of Belize. In this series of Webcasts, we visited a field research station located in the remote Chiquibul forests of the mountains of Belize. Find out what white flies have to smile about with entomologist Andrew Polaszek.

Why do many things sound different underwater? How are echoes made? Can you feel or see sound? Join us as we delve into the mysteries of sound. This webcast will feature an Aim High student demonstrating how to make a membranophone; Exploratorium physicist Dr. Paul Doherty modeling sound with ringing aluminum rods, corrugated plastic whirlies, and a slinky; and Marco Jordan, lead educator in the Exploratorium's Outreach program, demonstrating sound science with a "whine" glass and a singing bowl.
